ATTACHMENT FOR DENTAL MACHINES.

Specification of Letters Patent.

Patented Dec. 8, 1914:.

Application filed February 18, 1914. Serial N 819,539.

To all whom it may concern:

Be it'known that I, WILLIAM H. KING, a

citizen of the United States, residing at Blacksville, in the county ofMonongalia and State of Vest Virginia, have invented certain new anduseful 'Improvementsun Attachments for Dental Machines, of which thefollowing is a specification, reference be- L ing had to theaccompanying drawings.

This invention comprehends certaln new and useful improvements inattachments for dental machines, and has for its primary object toprovide anattachment of this character which will serve to catch orrecelve particles of gold and similar materials as the same dropfrom'fillingsduring opera-v tion of smoothing off and finishing thesame, thereby preventing a waste of this valuable material.

Another object is to providev a device of this character into which theparticles of material will fall, said particles finding their way to theretaining cup or receptacle which is detachably secured: to thelowermost ortion of a vessel.

A urther object is to provide a device of this character comprising avessel having a retaining cup or receptacle secured "thereto and adaptedto be secured beneath the instrument employed for smoothing-0E fillings,crowns, and bridge work.

A still further object is to provide a device of this character whichWill be of such construction that it may beemployed in connection withthe motor or grinding machine or with the lathe or any other machineemployed in the dental profession.

This invention has for still another object to generally improve andsimplify the construction of devices of this character and increase theefiiciency thereof, without increasing the cost of the 'same,'andprovide means whereby the particles of gold and similar materials usedfor fillings, crowns, and bridge work, and heretofore lost when ggindingdown or finishing the work, may

saved, thereby effecting a. great saving to the dental profession.

With the above and other objects in view,

my invention consists in certain novel constructions, comblnations, andarrangements of parts to be hereinafter more fully described, claimed,and illustrated in the ac companying drawings,- in which,

Figure 1 is a side elevational view of one form of my device; Fig. 2 isa sectional rected portion 6 is the several views, 1 designates an openmouthed vessel, preferably bowl-shape in form,'wh1ch may be formed ofrubber, aluminum, or other suitable material and which has one end lowerthan the opposite end with a depending neck or circular flange 2adjacent the lowermost end, upon which is threaded the retaining cup orreceptacle 3 for receiving or catching particles of gold and similarmaterials, a restricted opening 1 being provided in the lowermostportion of the vessel 1, whereby the filling material falling into thevessel may drop into the retaining cup or receptacle 3. The upper edges5 of too vessel 1 are turned inwardlv, whereby any fillin'g materialwithin the vessel will be prevented from falling out of the same, shouldsaid vessel be tilted. One side of the vessel is extended upwardly,adjacent the upper end of said vessel, as shown at 6, and said upwardlydirovided with 'a pair of spaced openings through which are engaged thescrews 8 having the nuts' 9 upon their inner ends. also extended throughthe right angled end 10 of the supporting arm 11. The supporting arm 11is curved transversely for engagement against the hand piece 12 of adental engine, and is provided with a longitudinal slot 13 having theset screw 14 engaged therethrough and upon which is mounted thesubstantially U- shaped spring clamp 15 for longitudinal adjustment uponthe supporting arm 11, the arms of said substantially U-shaped clampbeing adapted for engagement upon opposite sides of the hand piece 12 ofthe dental en ine, the roarm employed in the form The screws 8 aredental engine, the operator grasps both the handcpiece 12 and thesupporting arm 11 and may readily tilt the vessel 1 theproper directionto catch the particles of gold and the like which have heretofore beenlost when filing down or smoothing fillings, crowns, and the like. Itwill also be evident that owing to the construction of the vesseland themanner in which it is removably engaged with the hand piece, said vesselwill not interfere with the work of the dentist and all particles of thevaluable materials u sed will drop through the restricted opening 4t tothe retaining cup or receptacle 3.

When it is desired to employ this device in connection with the latheused by dentists, the supporting arm 11 is disconnected from the vessel1 and the free right angles fiattened portion 19 of the horizontal end20 of the rod 21 is secured upon the screws 8.

The main portion of the rod 21 is rotatably and slidably mounted in theupstanding end 22 of the bracket arm 23 and adapted to be secured inadjusted vertical and horizontal positionby the set screw 24:, itbeinglunderstood that the main or horizontal portionof the bracket arm23 is flattened and provided with openings25 to receive suitablesecuring members 26 for securing the same to the work bench upon which Ithe lathe 27 is positioned, said bracket arm 23 being positioned so thatthe rod 21 may be properly adjusted to place the vessel 1 beneath thewheel 28 of said lathe 27-whenthe lathe is in operation or to swing therod 21 to move the vessel 1 from beneath said wheel when not in use.

From the foregoing, it will be clearly apparent that I have provided adevice of this character of extremely simple construction and operationas well as cheap to manufac ture, and which will be highly eficient inuse and effect a saving of a quantity of valuable material employed bydentists for fillings, etc. I

' While I have shown the preferred embodiment of my invention, it willbe understood that minor changes in the details of construction andarrangement of parts may be made withinthe scope of theappended claims,without departing from the spirit of my invention or sacrificing any ofthe advantages of the same.

ma am What is'elaimed is 1. A device of the class described Ed in-"-prising a vessel, a supporting arm detachably connected to'the vesseland adapted and means carried by said arm for detachablyand adjustablyclamping the latter to the hand piece of a dental engine.

to overlie the hand piece of a dental engine,

2. A device of the class described comprising a vessel having adepending annular flange, a closure connected to said flange,

said vessel having an opening therein affording communication with saidclosure, and means carried by said vessel for support- 3. A-device ofthe class described comprising a'vessel having a depending flange, a

' receptacle connected to said flange, said vessel having an openingtherein communicating with the interior of said receptacle, saidvesselhaving an outwardly extending arm secured to one side thereof, and meanscarried by said arm for detachably holding the vessel below the underface of a dental engme.., I Y n d. A device of the character describedcomprising a vessel, a supporting arm projecting from said vessel andprovided with a longitudinal slot, means ad ustably mount- "ed upon saidarm for clamping the latter to the'hand piece of a dental engine, meanscarried by the last mentioned means and engaged through the longitudinal"slot of the supporting arm for securing said clamping means in adjustedposition longitudinally of the supporting arm, said vessel loeingprovided with an open ended slot to receive the shank of atool carriedby said hand piece, whereby the tool will be positioned above thevessel, and a retaining cup beneath said vessel.

5. A device of, the class described comprising a vessel having anupstanding wall at one side thereof, and means forv supporting suchvessel below a dental abrading tool, such upstanding wall being providedwith an open ended slot to accoodate the shanlr'of the tool.

In testimony whereof I hereunto afiiix my signature in the presence oftwo witnesses WILLIAM H. KING.
